UNATTENDED WHILE BURNING!
11. TROUBLE SHOOTING GUIDE
TROUBLE
Heater ignites but MAIN PCB
assembly shuts heater off after
a short period of time.
(Indicator Lamp is flickering and
room temp. display indicates " E1 ")
Heater will not ignite but
motor runs for a short period
of time.(Indicator Lamp is flickering
and room temp.display
indicates " E1 ")
Fan does not turn when heater
is plugged in and power switch
was in the " ON " Position.
(Indicator Lamp is on or flickering)
(Indicator Lamp is flickering and
room temp. display indicates "E2")
(Indicator Lamp is flickering and
room temp. display indicates "E3")
Heater will not turn-on
(Indicator Lamp is off)
POSSIBLE CAUSE
